Cannot read blueprints' titles when the dependecy tree is large

[Mounir Bsaibes]

Whenever the dependency tree grows, the blueprint titles become too small to read the blueprint title.
I see to possible solution (of course there may be better and other soultions):
1) expand the dependency tree area to accomodate larger number of blueprints.
2) provide an indent list of blueprints instead f the graph.
